Fig. 5

The positional shift of determined array shape for each epoch using sound speed models: constant gradient (blue triangle) and stratification model (yellow triangle). The shape for constant gradient model is displayed with the scale of axes. a Horizontal shift amount of the shape for stratification model is magnified by × 2000. Violet arrow denotes the estimated horizontal gradient vector and points in the direction of increasing sound speed. Blue arrow indicates the centroid shift. b Vertical shift amount is magnified by × 15. Horizontal axis indicates gradient axis for each epoch
